VuFind is a library resource portal designed and developed for libraries by libraries.
The goal of VuFind is to enable your users to search and browse through all of your
library's resources by replacing the traditional OPAC to include:

Catalog Records

Locally Cached Journals

Digital Library Items

Institutional Repository

Institutional Bibliography

Other Library Collections and Resources

VuFind is completely modular so you can implement just the basic system,
or all of the components. And since it's open source, you can modify the modules to
best fit your need or you can add new modules to extend your resource offerings.
